I'm about to buy heads for my stock bottom end 4.6 2v. Anyone have some for sale?
If TFS gains 35rwhp over PPIs then $1000 for 35rwhp is good. Then bigger cams and better cam timing because there’s more PTV clearance. Power all over the rpm range which is unusual for 4.6 cams or most aft. intake manifolds.I won't argue that tfs aren't better, its the $1000 difference that is hard to take.
